FIELD OF THE INVENTION

The present invention generally relates to a protective bag, and moreparticularly to a protective bag for a portable electronic device.

DESCRIPTION OF THE RELATED ART

With the development of technology, various portable electronic devices,such as a multimedia player (MP3, MP4 and so on), a cell phone, apersonal digital assistant (PDA), a hand-held game console, anelectronic book (E-book), a tablet personal computer (tablet PC), anetbook, a notebook and so on, have become an integral part of modernlife to many people. To compare with the traditional desk PC, a mainadvantage of the portable electronic device is easy to get carried.Therefore, in recent years, we can see people operating the portableelectronic devices anytime and anywhere.

In the above mentioned portable electronic devices, some are thehand-held game consoles, which comprise two bodies and these two bodiescan be folded/unfolded relative to each other. One body has a purescreen and the other has another screen and a plurality of buttons.Also, for the netbooks and the notebooks, a screen and a keyboard areconfigured on two bodies, which can be folded/unfolded relative to eachother. Accordingly, the screen can be supported by the other body tostand with an adjustable inclination, and thus the user can hold thedevice or put on a table to watch videos or operate.

Many users may use a protective sheath or a protective bag for theconvenience of protecting and carrying the portable electronic device.Currently, there are two main design types about the commercialprotective sheaths and the protective bags. In the first design type,one side edge of the sheath or the protective bag can be opened, andusers must unzip a zipper or unlock a fastener to open the side edge totake the portable electronic device out of the protective sheath or bagto use, and that is inconvenient.

In contrast, in the second design type, three adjacent side edges of theprotective sheath or bag are sealed with a zipper, the user can unzipthe zipper to directly unfold the sheath or bag, and then the user mayput the portable electronic device on an inner surface of the protectivesheath or bag to use directly. Besides, there may has two elastic tapes,bands or belts disposed on the inner surface for banding or hanging twocorners of the screen body of the portable electronic device, so as toavoid the protective sheath or bag directly dumping backward to collidewith other things after being unfolded.

However, the screen body of the portable electronic device is gettingthinner, and thus the screen body is not as easily to be banded tightlyas usual. Hence, the elastic tapes, bands or belts may loosely hang onthe screen body and thus the sight is affected when the screen body isflipped upward. Further, the elastic tapes, bands or belts may fall fromthe corners of the screen body when the screen body is flipped upward toa large angle, for example over 120 degrees. Moreover, in recent years,a gap between two bodies of the portable electronic device is designedto be narrower and narrower, and thus the elastic tapes. bands or beltsare improper to band the screen body.

Further, in other non-illustrated embodiments, theportable electronic devices may also be practiced to a netbook, ahand-held game console or the other kinds of portable electronic deviceshaving two bodies capable of being folded or unfolded relative to eachother.

The protective bag 100 comprises a first covering plate 110, a secondcovering plate 120 and at least a connecting component 130 connectedbetween a first side edge 112 of the first covering plate 110 and asecond side edge 122 of the second covering plate 120. In addition, thefirst covering plate 110 may further has a first fastener 114 disposedopposite to the first side edge 112, while the second covering plate 120may further has a second fastener 124 disposed opposite to the secondside edge 122. In this embodiment, the protective bag 100 comprises onlyone connecting component 130 connected between a middle portion of thefirst side edge 112 and a middle portion of the second side edge 122.However, in other non-illustrated embodiments, the protective bag maycomprise two connecting components connected between where adjacent totwo ends of the first side edge and where adjacent to two ends of thesecond side edge, or a plurality of connecting components arrangedaveragely between the first side edge and the second side edge.

Moreover, as illustrate in FIG. 3, the first covering plate 110 and thesecond covering plate 120 may be folded relative to each other about theconnecting component 130 formed as a shaft, so as to form a containingspace 102 for containing the portable electronic device 200. Herein, thefirst covering plate 110 covers a bottom surface 212 of the first body210, the second covering plate 120 covers a rear surface 222 of thesecond body 220, and the first fastener 114 and the second fastener 124are capable of fastening together, so as to hold the portable electronicdevice 200 between the first covering plate 110 and the second coveringplate 120. Thereafter, as illustrated in FIG. 4, the bottom surface 212may be carried on the carrying surface 300 via the first covering plate110, and the second covering plate 120 may stand on the carrying surface300 with a support provided by the connecting component 130 or leanagainst the rear surface 222 after users unlock the first fastener 114and the second fastener 124 and then unfolded the second body 220relative to the first body 210.

In detail, in the present embodiment, the first fastener 114 and thesecond fastener 124 may be formed from a zipper set. Furthermore, eachof the first covering plate 110 and the second covering plate 120 may bea plastic plate, the connecting component 130 may be a U-shaped plasticflat spring, and the first covering plate 110, the second covering plate120 and the component 130 may be integrally formed by injection moldingor thermoforming. However, in the other embodiments, the first coveringplate 110, the second covering plate 120 and the component 130 may beconnected by a manner such as fastening, attaching with adhesive,screwing, riveting and so on. As illustrated in FIG. 4, when a user isunfolding the second body 220 relative to the first body 210 after thefirst fastener 114 and the second fastener 124 are unlock (i.e. afterthe zipper set is unzipped), the second covering plate 120 is unfoldedrelative to the first covering plate 110 about the connecting component130 by the second body 220, and thus the connecting component 130 iselastically deformed. At this time, the second covering plate 120 leansagainst the rear surface 22 with an elastic restoring force provided bythe connecting component 130, so as to stand on the carrying surface300. Therefore, the second covering plate 120 is not only sightlier inuse, but also not likely to dump backward to collide with other thingsafter being unfolded.

Furthermore, in the other non-illustrated embodiments, each of the firstcovering plate and the second covering plate may be made from a metalmaterial or any other solid material capable of letting the connectingcomponent deform elastically and being rotated about the connectingcomponent with the elastic restoring force provided by the connectingcomponent. Besides, the connecting component can further be a metal flatspring, a torsion spring, a spiral spring, any other elastic componentwith the same functions or a combination thereof. In addition, a rangeof motion of an angle formed between the first covering plate 110 andthe second covering plate 120 is ranged from 0 degree to 150 degrees, soas to avoid forming an elastic fatigue of the elastic component due toan unfolded angle between the first covering plate 110 and the secondcovering plate 120 is too lager.

It should be noted that a free angle of the elastic component may bepreset as larger than 0 degree, for example 15 degrees as illustrate inFIG. 5. In such instance, the second covering plate 120 is unfoldedautomatically relative to the first covering plate 110 as long as thefirst fastener 114 and the second fastener 124 are unlocked, and thus itis convenient for users not only taking the portable electronic device200 out of the protective bag 100 but also unfolding the first body 210relative to the second body 220. As a result, the protective bag 100 ismore convenient in use.

Moreover, referring to FIG. 6 and FIG. 7, the connecting component 130may also be a shaft with a close fit structure commonly used in currentnotebooks. Hence, as illustrate in FIG. 6, an included angle between thefirst covering plate 110 and the second covering plate 120 may bemaintained with a friction provided by the close fit structure of theconnecting component 130. In another word, the second covering plate 120may stand on the carrying surface 300 with a support provided by theconnecting component 130.

FIG. 8 illustrates a perspective view of a shaft with a close fitstructure connecting the first covering plate and the second coveringplate according to an embodiment of the present invention, and FIG. 9illustrates a cross-sectional view of the shaft with the close fitstructure as illustrated in FIG. 8. Referring to FIG. 8 and FIG. 9together, in a preferred embodiment, the connecting component 130 cancomprise at least a shaft 132, a first metal sheet 134, and a secondmetal sheet 136. As illustrated in FIG. 8, in the present embodiment,the connecting component 130 comprises two shafts 132, and each of theshafts 132 is a combination of a nut N and a bolt B, so as to form theclose fit structure, wherein a tightness provided by the shafts 132 maybe adjusted by tightening or releasing the bolts B with the nuts N.Besides, each of the shafts 132 may provide a torque ranged from 3.5 to5.5 kgf-cm. In addition, a range of motion of an angle formed betweenthe first metal sheet 134 and the second metal sheet 136 may be rangedfrom 0 degree to 345 degrees.

The first metal sheet 134 is fastened to the first covering plate 110,the second metal sheet 136 is fastened to the second covering plate 120,and both of the shafts 132 are pivoted between a side edge of the firstmetal sheet 134 distant from the first covering plate 110 and a sideedge of the second metal sheet 136 distant from the second coveringplate 120. The detail structures of the second metal sheet 136 and theconnection between the second covering plate 120 and the second metalsheet 136 are described herein after, while the detail structures of thefirst metal sheet 134 and the connection between the first coveringplate 110 and the first metal sheet 134 are omitted herein due tosimilar to that of the second metal sheet 136.

In detail, referring to FIG. 9, the second covering plate 120 in thepresent embodiment may further have an inner surface 126, an outersurface 128, a first dent D1 formed on the inner surface 126, a seconddent D2 formed on the outer surface 128 and a slit S extending from theinner surface 126 to the outer surface 128. Besides, the second metalsheet 136 in the present embodiment comprises a first folded plate P1, asecond folded plate P2, a main plate P3, and a pivoting portion PP,wherein the pivoting portion PP comprises a connecting plate P4 and twocircular folded plates P5 (as shown in FIG. 8). The first folded plateP1 is embedded within the second dent D2. The second folded plate P2 isconnected between the first folded plate P1 and the main plate P3 andembedded within the slit S, i.e. the second folded plate P2 passesthrough the second covering plate 120. Part of the main plate P3 isembedded within the first dent D1, and the other part of the main plateP3 is extended outside of the second covering plate 120. The connectingplate P4 is connected between a side edge of the main plate P3 oppositeto the second folded plate P2 and the two circular folded plates P5.

Besides, each of the shafts 132 is fitted into one of the circularfolded plates P5 of the first metal sheet 134 and a corresponding one ofthe circular folded plates P5 of the second metal sheet 136. Thus, thefirst covering plate 110 and the second covering plate 120 may be foldedand unfolded relative to each other by the connecting component 130. Itshould be noted that since the tightness provided by the shaft 132 maybe adjusted by tightening the bolt B with the nut N, the second coveringplate 120 may stand on the carrying surface 300 with a support providedby the connecting component 130. Furthermore, as illustrated in FIG. 8,in the present preferred embodiment, the connecting plate P4(illustrated in FIG. 9) of the second metal sheet 136 may have a gap Gformed between the circular folded plates P5 (illustrated in FIG. 9),and both of the circular folded plates P5 (illustrated in FIG. 9) of thefirst metal sheet 134 are located within the gap G, and vice versa. Inaddition, as illustrated in FIG. 9, each of the first covering plate 110and the second covering plate 120 may further comprise a plurality ofenforcing rods R protruding from the bottom surfaces of the first dentD1 and the second dent D2 and passing through the first folded plate P1and the main plate P3, so as to tightly fasten the first folded plate P1and the main plate P3 on the first covering plate 110 and the secondcovering plate 120 respectively.

However, in the other non-illustrated embodiments, the structure of atleast one of the first metal sheet and the second metal sheet asillustrated in FIG. 8 and FIG. 9 for fastening to the first coveringplate and/or the second covering plate may further be replaced by amanner such as melt bonding, fastening, attaching with adhesive,screwing, riveting or a combination thereof. Furthermore, the connectingcomponent may further be practiced by a gear wheel structure, astructure screwed with nuts or other pivot structures commonly used incurrent notebooks as well. Besides, the first fastener may further be acrochet belt of a Velcro®, a male snap button of a snap button set, apermanent magnet, a hook or a pin, while the second fastener may furtherbe a velour belt of the Velcro®, a female snap button of the snap buttonset, a ferromagnetic material, a locking aperture or a insertingaperture, and vice versa. Alternatively, the first fastener and thesecond fastener may be permanent magnets with opposed polarities aswell.

Referring to FIG. 4 again, it should be noted that the connectingcomponent 130 and the first covering plate 110 and the second coveringplate 120 made from solid materials may damage the bottom surface 212and the rear surface 222 of the portable electronic device 200 in use,and thus the protective bag 100 is recommend to comprise an innermaterial layer 140. The inner material layer 140 covers the innersurfaces 126 of the first covering plate 110, the second covering plate120 and the connecting component 130 (for simplifying the figure, theinner surfaces of the first covering plate 110 and the connectingcomponent 130 are not illustrated in FIG. 4) for separating the portableelectronic device 200 from the first covering plate 110, the secondcovering plate 120 and the connecting component 130, and is made fromfiber cloth or other materials not likely to damage surfaces of theportable electronic device. Besides, the protective bag 100 may furthercomprise a lining cushioning material layer 150 disposed between theinner material layer 140 and the inner surfaces 126. In the presentembodiment, the lining cushioning material layer 150 may be made from atleast one of petroleum base foaming materials, EPE, EVA resins or E/VACresins, SBR, SCR or SCR resins, memory foams and foam rubbers, or othermaterials for buffering. In addition, the inner material layer 140 maymade from the above mentioned materials for buffering as well. Inanother word, the materials for buffering can also be exposed directlywithout covering the fiber cloth or the other materials for avoidingdamaging the surfaces of the portable electronic device 200 as long asit is ensured that the materials for buffering is not likely to damagethe surfaces of the portable electronic device 200.

Similarly, the protective bag 100 may comprise an outer material layer160 covering outer surfaces 128 of the first covering plate 110, thesecond covering plate 120 and the connecting component 130 (forsimplifying the figure, the outer surfaces of the first covering plate110 and the connecting component 130 are not illustrated in FIG. 4) aswell, and may be made from at least one of metal, plastic, leather,imitation leather, PU and cloth, or purely formed from a surface coatingor a surface treatment. Besides, the protective bag 100 may compriseanother lining cushioning material layer 170 disposed between the outermaterial layer 160 and the outer surfaces 128 as well. Similarly, thelining cushioning material layer 170 may be made from at least one ofpetroleum base foaming materials, EPE, EVA resins or E/VAC resins, SBR,SCR or SCR resins, memory foams and foam rubbers, or other materials forbuffering.

It should be noted that the present invention should not be limited tothe foregoing embodiments. In the other non-illustrated embodiments, theprotective bag may further not comprise the first fastener and thesecond fastener. In such instance, the first covering plate and thesecond covering plate may also hold the portable electronic devicetherebetween by the elastic restoring force or the friction provided bythe connecting component. Besides, the protective bag may furthercomprise at least one of a shoulder strap, a backpack strap and acarrying strap, and thus the protective bag is more convenient to becarried.

In summary, in the present invention, the second covering plate iscapable of standing on the carrying surface with a support provided bythe connecting component, and thus the protective bag provided in thepresent invention is sightlier in use and the second covering platethereof is not likely to directly dump backward to collide with otherthings after being unfolded. When the connecting component is practicedby using the elastic component, the free angle of the elastic componentmay be preset as larger than 0 degree, so as to let the second coveringplate being unfolded automatically relative to the first covering plateas long as the first fastener and the second fastener are unlocked, andthus the protective bag is more convenient in use.
